The realpath utility requires all paths exist when canonicalizing
symlinks. If /etc/resolv.conf points to a tmpfs, then it might
not exist initially. Use `readlink -f` so that we follow all
symlinks that are available.

Some shells (like dash) are lame and omit the POSIX increment/decrement
feature (because it is listed as optional). Tweak the shell script to
work in all POSIX variants.

Often it is desirable to have /etc/ be on read-only storage (well, the
whole rootfs) but have things like /etc/resolv.conf be symlinks to a
writable location. Tweak the simple script to support that.

Erik,
Attached is a patch for the udhcpc sample scripts, to correct the order in
which routers are applied if the DHCP server provides more than one (as per
section 3.5 of RFC2132).
Apologies for not being on the mailing list and thanks for your continued
efforts.
Simon.
